What buildpacks support SQLDB (DB2) with PHP for bluemix?

I'm developing a PHP webapp on bluemix with SQLDB (DB2). I cannot establish a connection to the database it seems, I can't access the data and I get SQLSTATE value: 08001. For connection I use getenv, VCAP_Services etc.. To deal with the DB2 modules I use a db2 buildpack: https://github.com/ibmdb/db2heroku-buildpack-php. However, looking on similar q&a's, it seems as the buildpack is no longer supported because of bluemix migration from lucid64 to cflinuxfs2.

My question is: Are there any modified (and free to use) buildpacks that supports SQLDB (DB2) with PHP for bluemix at the moment? Or can I possibly configure the buildpack my self?

After all my searches and troubleshooting I conclude that the buildpack is the crucial problem. Appreciate creative answers!
